Description
LCJ CV7SF2 wireless ultrasonic wind sensor
LCJ CV7SF2 is an LCJ wireless ultrasonic wind-sensor system with a solar-panel arrangement for applications where reducing mast or structure cabling is useful. The system still needs careful planning: sensor position, clear airflow, solar exposure, wireless communication, receiving equipment and final wind-data interface all matter. F&C Marine can help check the complete CV7SF2 installation before supply so the sensor and receiver arrangement suit the vessel or site.
Wireless ultrasonic wind measurement
The CV7 family measures wind electronically without conventional rotating cups or a vane. The wireless CV7SF2 arrangement changes how the measured data reaches the receiving equipment, but it does not change the need for correct sensor positioning. Nearby masts, aerials, rigging, superstructure and other obstructions can disturb airflow and affect readings. The sensor should be mounted in the cleanest practical airflow and aligned correctly to the reference used by the vessel or installation.
Solar and wireless installation planning
A solar-powered wireless sensor needs a mounting position that considers both airflow and exposure for the solar arrangement. Avoid locating the sensor where structures create persistent shading or where the wireless path is unnecessarily obstructed. The receiving equipment should be positioned and powered in accordance with the manufacturer documentation. On a refit, review the complete radio and sensor layout rather than assuming that an existing masthead position will automatically provide the best airflow, solar exposure and communication path.
Data interface and receiving equipment
Before ordering, identify which display, logger or navigation equipment will use the wind information and how the CV7SF2 receiver will interface with it. Different LCJ variants provide different interface options, so the exact product suffix and companion equipment matter. Record existing network or instrument connections and photograph any converter or junction unit. A wireless link can remove a mast cable, but the receiving side still needs reliable power and correctly configured data connections.
Commissioning and communication checks
After installation, verify that the receiver maintains a stable link with the sensor and that plausible wind speed and direction are displayed. Check physical sensor orientation, any pairing or configuration steps required by the manufacturer and the data at every receiving device. Observe operation over a useful period rather than relying only on a short test, especially where structures or vessel equipment may influence the wireless path. Record the final sensor and receiver locations and configuration for future service.
Maintenance and troubleshooting
Routine inspection should include the sensor body, solar arrangement, mounting hardware and receiving equipment. Look for contamination, physical damage, corrosion and anything that may shade the solar panel or obstruct the sensor. If wind data becomes intermittent, separate the fault into sensor, power, wireless-link and receiving-interface stages. Checking link status and receiver output before replacing the masthead sensor can prevent unnecessary component changes.
Documentation and related guidance
For manufacturer information, see LCJ Capteurs products and LCJ support downloads. Current LCJ documentation should be the final reference for solar installation, wireless pairing, interfaces and mounting. F&C Marine also provides an ultrasonic wind-sensor guide and the Marine Electronics Knowledge Base.

Before ordering LCJ CV7SF2
Send the vessel or site type, proposed sensor position, photographs of the mast or structure, receiving-equipment details, required wind-data interface and any existing wind system information. If this is a replacement for a fault, include symptoms and tests already completed. F&C Marine can then help confirm whether LCJ CV7SF2 is the right wireless solar wind-sensor arrangement and identify the receiver, interface and installation requirements before quotation.
